Sidestand
The sidestand is located on the left side
of the frame. Raise the sidestand or
lower it with your foot while holding the
vehicle upright.
TIP
The built-in sidestand switch is part of
the ignition circuit cu t-off system, which
cuts the ignition in certain situations.
(See the following section for an expla-
nation of the ignition circuit cut-off sys-
tem.)
WARNING
EWA10242
The vehicle must not be ridden with
the sidestand down, or if the sides-
tand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control.
Yamaha’s ignition circuit cut-off
system has been designed to assist
the operator in fulfilling the respon-
sibility of raising the sidestand be-
fore starting off. Therefore, check
this system regularly and have a
Yamaha dealer repair it if it does not
function properly.
EAU66771
Ignition circuit cut-off system
The ignition circuit cut-off system (com-
prising the sidestand switch and brake
light switches) has the following func-
tions.
It prevents starting when the side-
stand is up, but neither brake is ap-
plied.
It prevents starting when either
brake is applied, but the sidestand
is still down.
It cuts the running engine when the
sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-of f system according
to the following procedure.

Operation and important riding points
EAU15952
Read the Owner’s Manual carefully to
become familiar with all controls. If
there is a control or function you do not
understand, ask your Yamaha dealer.
WARNING
EWA10272

TIP
This model is equipped with:
a lean angle sensor to stop the en-
gine in case of a turnover. In this
case, the engine trouble warning
light will come on, but this is not a
malfunction. Turn the vehicle pow-
er off to extinguish the warning
light. Failing to do so will prevent
the engine from starting even
though the engine will crank when
pushing the start switch.
an engine auto-stop system. The
engine stops automatically if left
idling for 20 minutes. If the engine
stops, simply push the start switch
to restart the engine.

Braking
WARNING
EWA10301
Avoid braking hard or suddenly
(especially when leaning over to
one side), otherwise the scooter
may skid or overturn.
Railroad crossings, streetcar
rails, iron plates on road con-
struction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slow
down when approaching such
areas and cross them with cau-
tion.
Keep in mind that braking on a
wet road is much more difficult.
Ride slowly down a hill, as brak-
ing downhill can be very diffi-
cult.
1. Close the throttle completely.
2. Apply both front and rear brakes simultaneously while gradually in-
creasing the pressure.

Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:
Avoid high engine speeds during
acceleration.
Avoid high engine speeds with no
load on the engine.
Turn the engine off instead of let-
ting it idle for an extended length of
time (e.g., in traffic jams, at traffic
lights or at railroad crossings).
EAU16842
Engine break-in
There is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided.
EAU36532
0–1000 km (0–600 mi)
Avoid prolonged operation above 5100
r/min. NOTICE: After 1000 km (600
mi) of operation, the engine oil must
be changed, and the oil filter car-
tridge or element replaced.
[ECA11283]
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 6100
r/min.
1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.
NOTICE
ECA10311
Keep the engine speed out of
the tachometer red zone.
If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi-
cle.
